摘要：

The question of whether DNA is like a wire or an insulator is a controversial one, with some experiments finding DNA is conducting and some not. A new experiment suggests that it may all depend on the DNA sequence — electron transfer in DNA only occurs with high efficiency between guanine bases. This mechanism may help explain previous disparate results.
